map 转换 xml ； xml转map

public class MessageKit {

    public static String map2xml(Map<String, String> map) throws IOException {
        Document d = DocumentHelper.createDocument();
        Element root = d.addElement("xml");
        Set<String> keys = map.keySet();
        for(String key:keys) {
            root.addElement(key).addText(map.get(key));
        }
        StringWriter sw = new StringWriter();
        XMLWriter xw = new XMLWriter(sw);
        xw.setEscapeText(false);
        xw.write(d);
        return sw.toString();
    }
}



测试方法：

    @Test
    public void testMsg() {
        try {
            Map<String,String> maps = new HashMap<String, String>();
            maps.put("123", "abc");
            maps.put("bcd", "222");
            maps.put("bcd", "<abc>ddd</abc>");
            System.out.println(MessageKit.map2xml(maps));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

xml格式字符串转map

xml格式字符串：

<xml><ToUserName><![CDATA[gh_46265bed77c6]]></ToUserName><FromUserName><![CDATA[oUigKxHuNI-QMHKzvyYpw1lCY8VQ]]></FromUserName><CreateTime>1459927356</CreateTime><MsgType><![CDATA[text]]></MsgType><Content><![CDATA[sdf]]></Content><MsgId>6270340248959115708</MsgId></xml>

    public static Map<String,String> reqMsg2Map(HttpServletRequest req) throws IOException {
        String xml = req2xml(req);
        System.out.println(xml);
        try {
            Map<String,String> maps = new HashMap<String, String>();
            Document document = DocumentHelper.parseText(xml);
            Element root = document.getRootElement();
            List<Element> eles = root.elements();
            for(Element e:eles) {
                maps.put(e.getName(), e.getTextTrim());
            }
            return maps;
        } catch (DocumentException e) {
            e.printStackTrace();
        }
        return null;
    }
